What does an integrated-drive servo motor actually do on a PacDrive 3 line?
The ILM1402P11F0000 from Schneider Electric is a servo motor with integrated drive in the PacDrive 3 range — the device short name ILM flags the integrated-drive topology that puts the drive electronics inside the motor housing rather than in a separate cabinet, so the cabinet loses a node and the wiring collapses to a hybrid cable run to the PacDrive 3 controller. Continuous torque is rated at 12.5 N.m (continuous stall torque) and nominal working torque is 9.1 N.m, which is the figure to budget against in the machine sizing spreadsheet; peak stall torque reaches 55 N.m for the acceleration transients, so a sizing pass that ignores the 6× nominal-to-peak margin underrates the drive for any cycle that demands a fast index move.
Current, electrical constants, and what they mean at the controller shelf
Line rated current sits at 3.7 A and the continuous stall current at 4.8 A — that 1.1 A difference is the cooling margin between a stalled shaft at ambient and a free-running rotor, and on a natural-convection motor it disappears the moment the ambient climbs or the panel enclosure loses airflow. Maximum current Irms is 24 A, which is the figure the PacDrive 3 controller must source during the peak-torque pulse; the torque constant of 2.6 N.m/A (at 120 °C winding) means that 24 A delivers roughly 62 N.m of electrical torque at hot winding, comfortably above the 55 N.m peak-stall mechanical rating — the thermal envelope, not the amplifier ceiling, is what clips the pulse. Stator resistance of 1.9 Ω phase-to-phase at 20 °C drops to 1.32 Ω phase-to-neutral at 120 °C, and stator inductance falls the same direction from 22 mH to 11 mH — copper's positive temperature coefficient does the work here, and the drive's current loop must be tuned on the hot figure or the loop will be over-damped cold and under-damped at steady-state operating temperature. Back emf constant of 173 V/krpm at 20 °C is the speed-voltage ratio: at the 2000 rpm nominal speed the motor generates roughly 346 V back-emf, which sets the DC-bus ceiling the PacDrive 3 controller has to clear without tripping on overvoltage during a fast deceleration — a 750–800 VDC bus is the realistic minimum for clean regen at full speed.
Feedback, brake, and the mechanical envelope that decides the swap
Feedback is absolute single-turn SinCos Hiperface — that single-turn cap is the gotcha: it loses absolute position on power-cycle, so a vertical axis holding a load under gravity relies on the holding brake for the power-down event, not on the encoder remembering where it was. The holding brake is rated at 23 N.m — within 2.5× the nominal torque — which is the safety factor to check against the worst-case load on a vertical axis; a brake that just barely holds nominal torque at fresh lining will slip once the pad wears, and on a 9.1 N.m load this brake has usable margin. Shaft is keyed, 24 mm diameter, 50 mm long, with no second shaft end — the centring collar is 130 mm diameter and 3.5 mm deep on a 140 mm flange (4 mounting holes at 11 mm), which is the standard PacDrive 3 ILM footprint a replacement unit must match before the coupling and bolt pattern line up. Maximum radial force Fr drops from 2430 N at 1000 rpm to 1930 N at 2000 rpm — a belt or pinion drive applying force at the shaft end needs to be re-checked at the actual operating speed, not at standstill, because the bearing life curve degrades with the square of the speed increase once the rotor inertia term enters.
Environmental rating and where it actually mounts
IP54 is the ingress rating — protected against dust and splashing water from any direction, which suits a general factory floor or a panel-mounted machine but not washdown or food-grade lines where IP65 or higher is mandatory; natural convection cooling also means no fan to fail, but it caps continuous torque in a sealed enclosure above roughly 40 °C ambient. Mounting support is an international standard flange on a 140 mm motor flange size — that's a IEC-style bolt pattern that drops onto any PacDrive 3 machine bracket designed around the ILM frame size, and the 4-hole pattern at 11 mm is the standard M10 fit.
